A man pushes the wall and fails to displace it. He does
- A negative work
- B positive but not maximum work
- C no work at all
- D maximum work
Answer & Solution
Correct Answer
(C) no work at all
Step-by-step Solution
Detailed explanation
When man pushes the wall, then he does not produce any displacement in the wall. \(\begin{aligned} & \text {i.e., displacement }=0 \\ \therefore \quad \text { Work done } & =\text { Force } \times \text { Displacement } \\ & =\text { Force } \times 0=0 \end{aligned}\)
